I am not able to compare two files in sublime text 3. I have selected the two files I want to compare, however there is no Diff File option when searching for option through right click..
You have to install a package such as:
Sublimerge, FileDiffs, Diffy between others.
Once you have it installed, just follow the instructions of the creator.
